Answer:
180cm
Step-by-step explanation:
Vol of sphere = (4/3) pi r^3 and vol of cylinder = pi r^2 h
so
(4/3) pi 15^3 = pi (5)^2 h
(4/3) * 15^3 = 25h
h = [(4/3) * 15^3 ] / 25 = 180 cm
4x-2y=7 (1)
-3x+3y=10 (2)
3y= 3x+10
y= x+10/3 (3)
sub (3) into (1)
4x-2(x+10/3)=7
4x-2x-20/3=7
2x-20/3=7
+20/3 +20/3
2x= 41/3
x= (41/3) / 2
x= 41/6
sub x= 41/6 into (3)
y= 41/6+10/3
= 61/6
Therefore the point of intersection is (41/6, 61/6)
they are not congruent because
the sides, and noncongruent means “not congruent,” that is, not the same shape. (Shapes that are reflected and rotated and translated copies of each other are congruent shapes.) So we want triangles that look fundamentally different. But this is just a congruent copy of the triangle we have up above on the left. is the correct answer
Answer. A. 78.5 kg
Explanation. First, we must convert the lbs into grams, we can do this my multiplying 454 by 173 and get 78,500. Then convert it to kg, there are 1,000 g in a kg do divide 78,500 by 1,000 to get 78.5 kg. Let me know if it’s correct so others can use it. Brainliest would be appreciated.
Good luck :)
If a diameter intersects a chord of a circle at a perpendicular then the chord is bisected.
<h3>What is the relation between the chord and diameter of a circle?</h3>
- The segments of a circle whose endpoints are on its perimeter are called chords.
- A circle's diameter is the chord that passes across its center.
- The circle's longest chord equals its diameter.
- Any line that is perpendicular to a chord on the circle cuts it in half and goes through the center.
The solution to the problem:
A circle's chord is intersected perpendicularly by its diameter, which also passes through the center of the circle. The chord and diameter are perpendicular. Any line that is perpendicular to a chord on the circle and passes through its center divides it. The chord is divided equally by the diameter.
Therefore, the chord is bisected.
